The Laboratoire d’Ingénierie des Fonctions Moléculaires is a modeling research team whose focus sits right at the interface between the domains of life science and material science. Our working approach is to start from problems of medical and/or technological relevance and develop computational strategies to provide an orthogonal and hopefully insightful view. Fundamental questions concerning with molecular self-assembly, the allosteric regulation of important neurotransmitter receptors, and the development of efficient numerical strategies to compute the free energy in solution are being tackled.
